Difficulty in the datarate transfer

Hello matlab geeks, I have created a small simulation of QPSK modulation with FH algorithm. Please find the link for my simulation model in the below. http://www.box.net/shared/aj8gv2ybrqkx52kimte1

I problem is well the transmitted and received symbols seems to be same when i run the simulation, and its perfect. But when i flush it to the workspace, its totally messed up. the received symbols are very huge. I believe the rate of the hoppinh Freq generator is very high, but i have no idea, why is that i look perfect in Display but not in the workspace. I tried a lot but could't get perfect solution, can anyone please help me with this one?? also u can send me mail to [e-mail]

- thanks in advance
